In case anyone in the UK who has Sky+ is interested, you can now set your Sky+ box to record programmes remotely via text message using the Sky by mobile software (available from Sky.com). All you need is a sky.com account, and a Sky+ box. Once you have registered with Sky.com, go to Interactive (on your Sky+/Sky HD box) then go to Sky Customer Services. Press Green for A-Z, then 7 or P-S. Select Remote Record and it will give you the option to register.
It will require a phone connection as well as your sky.com username and password. Finally, you will be asked for your mobile number and that's it! A great feature and compatible with Blackberry phones.
